To all whom it mayconm: Y

- Be it known that I', ,ALnn'rfWnmraMsfa citizen of the UnitedStates,

- Louis,Missouri, have invented acertain new rand useful Improvementin Vehicl'eWheels; of which the following is a ful-1,. clear, and exact description, such-as will enable others skilled in the art to which itappertains to make and use the same,` reference being had l drawings,j forming 1 Y Figure l'is anv elevational view-of my proved device partlybroken awayl in Aorder to show certain detailv construction. Fig." 2

vis a sectional detail view of vthe hubv of the wheel. Fig. 3 is a sectional detail of the rim and-tireof-the-wheel. My invention relatesto an improvementy in wheels to be used'o'n any type of vehicles, vand especially in automobile construction.

:One .of `the objects of my invention is to known provide a vehicle wheel -which advantages Aof the pneumatic featureof 4Vwheels now 1 'defects i. It is a well known fact that-'the ordinary :has all the ny common use and avoids their pneumatic tire is very lezqoensiv'e as toirst cost, and also'as to repair..- It is also wellv vthat the ordinary solid ti-re' construction on vehicle wheels: is not satisfactory as there is not enough resiliency in the' tire to 4 o iset the vibrationproduced because-of the irregularity of he surfaces upon which the wheels are moved, land therefore,' these wheels do not absorb vor' regulate the vibration to produce easy motion of the `vehicle.

It ismy idea to 'take` advantage of the re i siliency' of compressed airin 'the wheel lconstruction and-yetV make use of the solid rubbertirel 4 'l l.

Referringto the. drawings, 1 indicates genl erallythe rim offthe wheel,v `2 thespokes periphery so.

Aand 3 thehub.

The rim 1 is comprisedlof two overlappingv setsA of .sectional parts,.-"4 and5 respectively.I The parts 4 asiindicated in Fig. 3 are shaped with a flat periphery 6 having slightly an. gular corners 7 ateach edge. Opposite the the portion 4 is grooved as' at 8 for the reception ofthe sections 5. The sec-l tions 5, are? suitably shaped to lit in the oove 8, and are curved on their outer erlphery as indicated s on' Fig. are separated to form4 residing at St. v ,and `recede from each other.

inclined-slots 10 and 11 in order to allow the ad]acent sections 4- and `5 to approach The spokes 2 are comprised of a head por tion -12 and 'telescopic intermediate portions.

13"'l and 14. The head portion 12 is shaped "on its interior to fit snugly over the interengagin arrange :sections 4 and 5, and the spokes-are so that these head portions overlap the sections 4 and 5 wherever there is a slot 10 or 11 between .adjacent sections 'of the rim. It should vbe noted that one-'head v12 overlaps a slot 10 in the outer section 4 and the-next head 12 overlaps a slot 11 in the inner section's. In this manner the sections 4 and 5 break joints. The heads -12 are at tached to the sections 4 and 5 which are not broken away to Vform the slots 1Q or 11,.,by means of screws 15 and 16. mediate portion of thev spoke 2 which isl designated 13 is solid and is screw threaded at 17 into each head 12. The portion 13 is The interi z connected tothe portion14 which is also nted the hub 3.

As seen from ig. 2 the hub 3 is formed with v'a' bearing for `the axle at 18, and is formed with a screw 19 having a,fcountersunk portion 20 at'the telescopically mo threaded end portion end.4 lScrewed onto the portion 19 isa capH 21 with a flat face 22 having a groove 23 cut therein, andan opening 24 boredthttough from the outside of the cap to the groove. l

screw cap 25.

AOn the face ofthe hub 3 whiehengages i adapted to' be seated against the curved'face ,ot the bushing 27. .If desired a small spring [may be introduced into the bushing 26 to keepthe ball 28 seated against the end ofthe' bushing27.v

29 is a slot extending from thebushing 26 through the hub to an opening formed in the lspoke 2.

This `opening 30 is bored in a sleeve 31 which 'is screw threaded into the yhub and extends upward vfrom the passage way 29 through the' hub 3 and inside the-teles- The section 14'slides over 'the hollow4 -Mounted on this opening 24 is the ordinary 27 screwed therein lwith a ball valve "28 cess 32 formed around the hub. The hub 3 on its outer periphery is formed in a series of projections 33 through which the telescopic member 14 passes. In order to ,form a tight joint at this point al packing ring 34 is introduced .at the end of the projection 33 and the projections are suitably formed with an external threaded portion in order that a cap 35 may be screwed thereon tohold the packing ring 34 in place.

Q Extending into the recess 32 is an opening 36 having a screwed cap 37 fitted thereover.

'This recess 32, by means of the opening 36,

is kept filled with oil or' water or other suitable liquid in order to keep the joints between the sliding section 13 and the sleeve 31 air tight. The liquid vlilled'recess also acts to form a cushion in the spoke section 14, lso that when a spoke is pressed in at one sideof the wheel this pressure will be e transmitted through the liuld to a Spoke on v the oppositeside of the wheel-'to push this spoke out and thereby cushionthe shock on'the wheel produced by striking an obstruction. l

Mounted on the outside periphery of the` outer section 4 of the wheel is a solid rubber tire 38 of ordinary fiat construction.

To keep my wheel in expanded position it Vis only necessary to unscrew the -plug 25 and pump air through the opening 24 into the grooves 23 and from there past the ball valves ,28 through lthe openings 29 `and,30,

l and into the interior ofthe sleeves 31 and telescopic portion 14 to press finally againstv the solid portion 13 of the spoke.

As the rim 1 is made up of sections which 4are capable of ex ansion to increase the pe riphery of the W eel, and as the tire '38 is capable of being expanded to increase its periphery, it is clear thaty my improved wheel 'is held in the v.expanded position by means oi the compressed air lintroduced into the hub and spokes, and therefore, any shock or vibration due to unevenness in the y roadway may be taken up not by the tire,

but through the resiliency of the spokes.

a- In a vehile wheel, a hollow hub fined' with liquid, a series of spoke sections extending through the liquid and screw seated in the central portion of the hub, telescoping sections mounted on said spoke sections,

'and extending through the outer portion of the hub, outer spoke sections seated in the outer ends ofthe telescoping sections, a rim on the outer ends of the outer spoke sections, and a tire on said rim.

4. In a vehicle wheel, a hub, hollow spokes attached to the hub, means whereby compressed air may be introduced into the hollow spokes, comprising a groove connected with each spoke, a ball valve within the groove, and a cap applied to\ the hub having a continuous groove connecting with each groove communicating with the spokes, and a connection from the outside of the cap`to the continuous groove therein.

5. In a vehicle wheel having a hub, hollow sectional s okes, and a sectional rim, means for introducing compressed air withinthe hollow spokes, a chamber within the hub filled with` liquid which entirely sur-4 rounds the joint between a pair of the hollow sectional members of each spoke.

6. vIn a vehicle wheel having a recessedhub, telescoping hollow spokes, having one section ,attached to the hub, means whereby compressed air may be introduced into the hollow spokes, and liquid within the recess in the hub forming a cushion for a section of the sp'oke telescoping the section attached to the hub.

7. In a` vehicle wheel, a recessed hub,

spokes comprising telescopic sections, one section being attached to the hub, and the other telescoping the first section extending within the recess in the hub, means for introducing compressed air within the lixed, 'section of the spoke, and means for introducing liquid within the recess inthe hub. In testimony whereof I hereunto affix my signature in the presence of two witnesses, this 20 day of August, 1910.
